Agronomic Yield of Perennial Crops ; treatments G5 - G10

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Agronomic yield from the poplar trees and the 5 herbaceous perennial crops; switchgrass, miscanthus, mixed grasses, old field and native prairie. These treatments are part of the GLBRC Biofuel Cropping System Experiment located on the Arlington and KBS GLBRC Intensive sites. Yield data for these treatments are given as dry matter.

Microplots were established on the perennial crops to look at the affects of fertilization on yield. Treatments G5, G6, G7, G8, G9 are normally fertilized so the microplot was unfertilized and G10 does not receive fertilizer so the G10 microplot was fertilized.

This datatable is part of the GLBRC Agronomic Yields dataset. This data set contains information about agronomic yields for the GLBRC Biofuel Cropping System Experiment, the Stover Removal Experiment and the Unfertilized/fertilized Experiment at Kellogg Biological Station and Arlington and also for the GLBRC Scale-up experiment and Switchgrass N-rate experiments at KBS. Perennial treatments include herbaceous perennials- switchgrass, miscanthus, grass mix, old field and prairie (G5,G6, G7, G9 and G10) and poplar trees (G8) . Annual treatments include continuous corn (G1), and during 2008-2011 corn-soybean–canola rotations (G2-G4). In 2012 ,G2-G4 treatments no longer planted canola and added cover crops to a corn-soy rotation. Agronomic yields are measured during normal crop harvest by machine harvesters appropriate to each crop as described in the GLBRC Agronomic Protocol.
